Objective
This proposed project is aimed at theoretical and experimental investigations of geophysical phenomena, which are directly or via a change of interactions connected to the existence of the ionospheric Alfvén resonator (IAR). Active and passive roles of IAR in formation of ULF electromagnetic environment (in frequency range 0.1-10 Hz) at the ground and in near space will be studied in detail.
For the first time, detailed correlated study of IAR fingerprints such as spectral resonance structures (SRS) frequently observed at high, mid and low latitudes will be performed. Long-term statistical surveys and selected case studies will be carried out. Properties of SRS will be used in an inversion technique to infer ionospheric parameters and to apply SRS as a monitor for large-scale ionospheric modulation by gravity and planetary waves.
Past and current satellite data will be searched for IAR signatures in space. The role of IAR in formation of ULF wave spectra in the inner and auroral magnetosphere will be investigated intending to resolve principal problems of the near-Earth environment. In particular, the influence of reflection from and transmission through the ionosphere on generation and detection of various spectral forms in Pc 1 frequency band, such as pearls and IPDP emissions, will be studied. The Alfvén Sweep Maser (ASM) model of which IAR is an essential component will be tested for its functionality in the production of Pc1 ULF waves. The missing link of ion precipitation in the experimental verification of ASM will be addressed in a special co-ordinated multi-satellite-ground observation approach. This study will essentially help in quantifying the contribution of ULF waves to the particle and energy budget of the magnetospheric ring current.
Considerable theoretical efforts will be made to improve present IAR models taking into account non-linear effects, new excitation mechanisms, and new constituents of the near-Earth environment such as dust and aerosols. The IAR concept will be enlarged by applying it to small-scale auroral physics and substorm triggering.
